What is the SEER (Seasonal Energy Efficiency Ratio)?

A series of uniform test conditions resulting in a value used to approximate the total annual heating requirements divided by the total electric power used. This rating is a combination of part load and full load performance, as well as cycling losses. Thc higher the SEER, the more efficient the system in the cooling cycle.

In addition to comfort, you'll notice far greater efficiency.

Because heat pump systems move heat that is already supplied by nature, less energy is required to condition the air in your home. This results in greater efficiency, comfort and savings. Your overall efficiency, however, will vary among heat pump systems, depending on the model and manufacturer you select.

Before you purchase a heat pump system, look for the SEER/HSPF information provided. Each is a standard measure of a heat pump system's heating and cooling efficiency and is the best way to identify which system is best for your needs. The Seasonal Energy Efficiency Ratio (SEER) gives annual cooling requirements divided by the total electric power used. And the Heating Seasonal Performance Factor (HSPF) measures annual heating requirements divided by the total electric power used. Two additional means of measuring the efficiency of a heat pump system are the Coefficient of Performance (COP) and Energy Efficient Ratio (EER). During the past two decades, great improvements have been made in all of these categories.

The SEER/HSPF of the heat pump system you purchase directly affects your energy costs. The higher SEER/HSPE, the lower you can expect your heating and cooling costs to be. The lowest efficiency heat pumps manufactured today are substantially more efficient that those available only a few years ago.
